BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be specifically described below with reference to the drawings showing its embodiments.
FIG. 1 is a conceptual diagram showing a procedure for performing clinical examination. In a medical institution such as a hospital or a clinic, the content of a clinical examination is determined for a subject, and an examination request is created in which the content of the clinical examination is recorded. A clinical test in this embodiment is a sample test performed using a sample collected from a subject. The content of the clinical examination is determined by the doctor who examined the subject. The specimen is, for example, a bodily fluid such as blood, saliva, runny nose, tears, sweat, spinal fluid, or urine. Alternatively, the specimen may be, for example, nasal swabs, laryngeal swabs, feces, cells, or the like. A sample is then taken from the subject. This embodiment mainly shows an example in which the specimen is blood.

Specimens are sent from medical institutions to testing institutions. The laboratory is an institution external to the medical institution or a laboratory department inside the medical institution that performed the examination. The laboratory receives the sent specimen. Next, a clinical test is performed according to the test request. In clinical examinations, specimens are examined. The test results are then reported to the medical institution. The test support method according to the present embodiment supports the implementation of clinical tests, and particularly supports the work performed when samples are collected from subjects.

A specimen collected from a subject is contained in a specimen container. FIG. 2 is a schematic diagram showing an example of a sample container 6 that holds a sample. For example, the specimen container 6 is a blood collection tube. The sample container 6 is made of a transparent material such as glass or resin and has a tubular shape. One end of the sample container 6 is closed and the other end is open. After a sample such as blood is placed inside the sample container 6, the sample container 6 is fitted with a lid, and the inside of the sample container 6 is hermetically sealed. The sample container 6 may have a shape other than a tubular shape, and may be made of an opaque material. A label 61 on which a sample container ID is recorded is attached to the sample container 6 . For example, the label 61 has a barcode representing the sample container ID.

The sample container ID includes information indicating the type of the sample container 6 and information specific to the sample container 6 and for identifying the sample container 6 . The sample container ID corresponds to container identification information. The sample container ID may be recorded on the label 61 in a form other than a barcode, such as a two-dimensional code. The sample container ID may be recorded directly on the sample container 6 by a method such as writing a barcode directly on the sample container 6 . The specimen container ID may be recorded in the specimen container 6 as electronic data. For example, an RF (Radio Frequency) tag storing a sample container ID may be attached to the sample container 6 , or a memory storing the sample container ID may be attached to the sample container 6 .

The sample container 6 is delivered to the medical institution with the sample container ID recorded in advance. For example, the sample container 6 is delivered to the medical institution with the label 61 having the sample container ID recorded thereon attached in advance. At the medical institution, the task of assigning the sample container ID to the sample container 6, the task of recording the sample container ID in the database, and the task of attaching the label 61 to the sample container 6 are not performed. A specimen collected from a subject is stored in a specimen container 6 . By transporting the specimen container 6 containing the specimen from the medical institution to the testing institution, the specimen is sent from the medical institution to the testing institution.

The storage device 1 receives the inspection request transmitted from the input device 201 by the communication unit 15 . The calculation unit 11 of the storage device 1 records the inspection request in the subject DB 132 in association with the subject ID. The calculation unit 11 determines one or a plurality of inspection items specifying specific inspection contents according to the contents of the inspection request, and records information on samples necessary for executing the inspection items in the sample table 133. .

FIG. 6 is a conceptual diagram showing an example of the contents of the sample table 133 before samples are collected. In the sample table 133, in association with the inspection request ID, the sample container type, sample container ID, status, total sample collection amount, inspection item, dispensing amount, confirmation item, confirmation item content, and confirmation of confirmation items are essential. or optional, and a confirmation input URL (Uniform Resource Locator) is recorded. The test request ID is information for identifying one clinical test requested for one subject. The inspection request ID corresponds to inspection identification information. The test request ID is information specific to one clinical test. The calculation unit 11 records the inspection request ID in the subject DB 132 in association with the subject ID. In the example shown in FIG. 6, "001" is recorded as the inspection request ID.

The sample container type indicates the type of the sample container 6 for containing the sample collected from the subject. The sample container type corresponds to container type information. The sample container ID is information unique to each sample container 6 and is recorded in the sample container 6 as described above. Information indicating the type of sample container 6 included in the sample container ID may be represented by the same code as the sample container type, or may be represented by a different code. Status indicates the state of the sample. The total specimen collection amount is the collection amount of the specimen contained in the specimen container 6 . The storage temperature is the temperature at which the sample is stored. A dispensed volume is the amount of sample required to perform a test item. The confirmation item is information that needs to be confirmed when executing the inspection item. The confirmation item content is the content of the confirmed confirmation item. Confirmation items include information that must be confirmed and information that is optional, and either one is specified. The confirmation input URL is a link for inputting confirmation items.

One or more test items are performed in one clinical test. In the example shown in FIG. 6, inspection W, inspection X, inspection Y, and inspection Z are performed, and inspection W, inspection X, inspection Y, and inspection Z are recorded as inspection items in association with inspection request ID "001". It is The necessary amount of sample is determined according to the inspection item, the dispensed amount is determined according to the inspection item, and the dispensed amount is recorded in association with the inspection item. The storage temperature of the sample is determined depending on the inspection item, and the storage temperature is recorded in association with the inspection item. The relationship between inspection items and other information such as the amount of dispensing is recorded in advance in a database, and the database is stored in the storage unit 13 . The calculation unit 11 reads information related to the determined inspection item from the database, associates the read information with the inspection item, and records them in the sample table 133 .

Depending on the inspection item, the criteria for determining that it is abnormal may differ depending on the condition of the subject, such as sex, age, or weight. As for such inspection items, it is desirable to confirm the condition of the subject, and the condition of the subject such as sex, age, weight, etc. is recorded as optional confirmation items. Depending on the test item, it is essential to designate a drug that reacts with the sample for testing. For such inspection items, drug names are recorded as essential confirmation items. In the example shown in FIG. 6, the content of the confirmation item has not yet been entered and is blank.

Specimens related to a plurality of test items having the same storage temperature can be accommodated and stored in the same sample container 6 . When samples related to multiple test items are contained in one sample container 6, the multiple test items are recorded in association with one sample container type and sample container ID. In the example shown in FIG. 6, examination W and examination X are associated with the specimen container type "specimen container A". This means that the samples for the test W and the test X are collectively accommodated in one sample container 6 whose sample container type is “sample container A”. The sum of the dispensed amounts associated with a plurality of test items using the specimen contained in one specimen container 6 is the total specimen collection amount.

In the example shown in FIG. 6, the status is "uncollected" because the specimen has not yet been collected. Since the sample container in which the sample is stored is undetermined in the uncollected state, the sample container ID is blank. Similarly, in the sample table 133, information about samples is recorded in association with each of a plurality of test request IDs. If the sample is other than blood, the sample table 133 may record information indicating the type of sample.

The content of the sample table 133 as shown in FIG. 6 is determined by the calculation unit 11 according to the content of the test request according to the computer program 131 . Alternatively, the storage unit 13 stores a guideline table that records a guideline for determining information about a sample according to the contents of an inspection request, and the calculation unit 11 stores the contents of the sample table 133 according to the guideline table. may decide. The storage unit 13 that stores the sample table 133 corresponds to the storage unit of the examination support device.

FIG. 7 is a flowchart showing an example of a procedure of processing for assisting sample collection executed by the inspection support system 100 . A step is abbreviated as S below. The calculation unit 11 of the storage device 1 executes processing according to the computer program 131 , and the calculation unit 21 of the collection assistance device 2 executes processing according to the computer program 241 .

Before the operator 51 collects a sample, the collection support device 2 reads out information about sample collection from the sample table 133 and outputs it (S1). In S1, for example, the operator 51 who performs the work of collecting a sample from a subject operates the operation unit 25 while facing the subject to specify the subject or the test request. information to the collection support device 2 . For example, the name of the subject, the subject ID, or the like is input as information for specifying the subject. For example, a receipt number, an inspection request ID, or the like is input as information for specifying the inspection request. Information for specifying a subject or an examination request may be acquired by the reading unit 27 .

The calculation unit 21 transmits information for specifying the subject or the examination request from the communication unit 28 to the storage device 1 via the communication network N. FIG. The storage device 1 receives information for specifying a subject or an examination request by the communication unit 15 . In the subject DB 132, information for specifying the subject including the subject ID and information for specifying the inspection request such as the inspection request ID are recorded in association with each other. When the inspection request ID is unknown, the calculation unit 11 reads the inspection request ID associated with the information for specifying the subject or the inspection request from the subject DB 132 . The calculation unit 11 reads out from the sample table 133 the information related to sample collection associated with the test request ID. Further, the calculation unit 11 reads personal information of the subject associated with the inspection request ID from the subject DB 132 . The calculation unit 11 transmits the read information from the communication unit 15 to the collection support device 2 via the communication network N. FIG. The collection support apparatus 2 receives the information at the communication unit 28, and the calculation unit 21 outputs the information regarding the collection of the sample by displaying the collection support image representing the information regarding the collection of the sample on the display unit 26. FIG.

FIG. 8 is a schematic diagram showing an example of a collection support image. The collection support image includes the date of receipt of the test request, the reception number of the test request, the date of sample collection, and the subject ID, and also includes the subject's personal information such as name and gender. there is Furthermore, the collection support image includes an inspection request ID, and includes the sample container type, sample container ID, and total sample collection amount associated with the inspection request ID. The calculation unit 21 creates a collection support image according to the information received from the storage device 1 and displays the collection support image on the display unit 26 . Information related to sample collection is displayed by displaying the collection support image.

There is one inspection request ID per inspection. When a plurality of sample container types are associated with the test request ID, the plurality of sample container types are displayed, and the sample container ID and total sample collection amount associated with each sample container type are displayed. In the example shown in FIG. 8, the sample container ID has not yet been acquired, and the sample container ID is blank. In this manner, information regarding sample collection, including the test request ID and sample container type, is output. By displaying the sample container type, the operator 51 can confirm the type of the sample container 6 that should contain the collected sample.

The collection support device 2 next outputs a confirmation request for personal information of the subject (S2). In S2, for example, when the operator 51 operates the operation unit 25 to specify a display portion of the subject's personal information on the collection support image by a method such as clicking, the operation unit 21 An image showing a personal information confirmation request is superimposed on the collection support image and displayed on the display unit 26 .

FIG. 9 is a schematic diagram showing an example of an image representing a personal information confirmation request. An image representing the subject's name and sex in characters is displayed superimposed on the collection support image. The calculation unit 21 creates an image based on the received personal information of the subject and displays it on the display unit 26 . In the example shown in FIG. 9, the name and sex of the subject are displayed, and confirmation of the name and sex is prompted.

The collection assistance device 2 then accepts confirmation of the subject's personal information (S3). In S3, for example, the worker 51 confirms the name and sex of the subject himself/herself, and the operator 51 operates the operation unit 25 to input confirmation of the personal information of the subject. , to obtain information indicating that the subject's personal information has been confirmed. In the example shown in FIG. 9, confirmation of personal information is input by designating a portion representing "OK" on the image by a method such as clicking. By confirming the subject's personal information, it is confirmed that the person from whom the specimen is collected is the subject of the clinical examination. After receiving the confirmation of the personal information, the calculation unit 21 adds a mark indicating that it has been confirmed to the personal information of the subject included in the collection support image.

In S3, the subject himself/herself, not the operator 51, may operate the operation unit 25 to input confirmation of the subject's personal information. In the example shown in FIG. 9, when there is no confirmation of the personal information of the subject, such as when the part representing "cancel" is specified, the calculation unit 21 may end the processing, and the processing starts from S1. may be resumed.

In S2 and S3, the collection support device 2 may accept confirmation of personal information other than name and gender. For example, when the information indicating that the subject is difficult to collect blood and the blood collection history are recorded in the subject DB 132 in association with the subject ID, the calculation unit 21 displays a request for confirmation of the blood collection history. The resulting image is displayed on the display unit 26, and confirmation is accepted. For example, as the blood sampling history, the body part from which the previous blood sampling was performed is displayed and confirmed. By confirming the blood collection history, precautions to be taken in blood collection are known, and the difficulty of blood collection is reduced.

The collection support device 2 then outputs an image of the sample container 6 in which the collected sample is to be stored (S4). In S4, the calculation unit 21 superimposes the image of the sample container 6 indicated by the sample container type associated with the test request ID, that is, the sample container type included in the collection support image, on the display unit 26 on the collection support image. indicate. For example, the storage unit 13 of the storage device 1 stores in advance the image data of the sample container 6 associated with each sample container type, and the collection support device 2 reads the image data from the storage device 1, 21 creates an image of the sample container 6 based on the image data and displays it on the display unit 26 . The image data may be stored in advance in the storage unit 24 of the collection assistance device 2 .

FIG. 10 is a schematic diagram showing a display example of the image of the sample container 6. As shown in FIG. A mark 261 indicating that it has been confirmed is added to the name and sex of the subject. An image of the specimen container 6 is also displayed. In the example shown in FIG. 10, three types of sample container types are associated with the test request ID, so images of three types of sample containers 6 are displayed respectively. By displaying the image of the sample container 6, the operator 51 can confirm the appearance of the sample container 6 in which the sampled sample is to be stored. Specimen containers 6 of different types have different appearances such as color, size or shape. In the example shown in FIG. 10, sample containers 6 of different types have caps of different colors. By checking the appearance of the sample container 6 , it is possible to effectively prevent the operator 51 from mixing up the sample container 6 with the wrong type of sample container 6 .

The collection support device 2 then acquires the sample container ID of the sample container 6 that should contain the sampled sample (S5). In S5, the operator 51 selects the sample container 6 to be actually used, the reading unit 27 reads the sample container ID from the sample container 6, and the computing unit 21 acquires the read sample container ID. For example, a plurality of types of sample containers 6 are prepared at the operator 51, and the operator 51 selects one sample container 6 having the same appearance as the sample container 6 whose image is displayed on the display unit 26. The reading unit 27 reads the sample container ID recorded in advance in the sample container 6 . For example, the worker 51 brings the reading unit 27 closer to the sample container 6 and the reading unit 27 reads the barcode recorded on the label 61, whereby the sample container ID represented by the barcode is read. When the RF tag is attached to the sample container 6, the reading unit 27 reads the sample container ID recorded on the RF tag using short-range wireless communication.

The collection support apparatus 2 then determines whether or not the type of sample container 6 indicated by the acquired sample container ID matches the type of sample container 6 indicated by the sample container type (S6). The sample container ID includes information indicating the type of sample container 6 . In S6, the calculation unit 21 determines whether or not the type of sample container 6 indicated by the information included in the sample container ID matches the type of sample container 6 indicated by the sample container type associated with the test request ID. do. If the type of sample container 6 indicated by the acquired sample container ID does not match the type of sample container 6 indicated by the sample container type (S6: NO), the collection support apparatus 2 determines that the types of sample containers 6 are different. error is output (S7).

FIG. 11 is a schematic diagram showing an example of an error indicating that the types of sample containers 6 are different. In S7, the calculation unit 21 displays on the display unit 26 a collection support image indicating an error as the sample container ID. Further, the calculation unit 21 creates an error image including a notification that the sample container 6 to be used is different and an image of the correct type of sample container 6, and displays it on the display unit 26 superimposed on the collection support image. do. It is displayed that the type of sample container 6 to be used is different, and an image of the correct type of sample container 6 is displayed. In the example shown in FIG. 11, errors and images are displayed for multiple types of sample containers 6 whose sample container IDs have not yet been acquired. If there is one type of sample container 6 whose sample container ID has not been acquired, an error and an image are displayed for the one type of sample container 6 .

An error is output when the operator 51 selects the wrong type of sample container 6 and acquires the sample container ID from the wrong type of sample container 6 . Therefore, it is possible to reliably prevent the wrong type of sample container 6 containing the sample. Further, by displaying the image of the correct sample container 6, the operator 51 can reconfirm the appearance of the correct sample container 6 to be used.

After S7 ends, the collection support device 2 returns the process to S5. For example, when the operator 51 operates the operation unit 25 to designate a portion representing "cancel" on the image, the calculation unit 21 terminates the output of the error image and proceeds to S5. return to

If the type of sample container 6 indicated by the acquired sample container ID matches the type of sample container 6 indicated by the sample container type (S6: YES), the storage device 1 associates the test request ID with the sample container type. The sample container ID is stored (S8). In S<b>8 , the calculation unit 21 transmits the acquired sample container ID from the communication unit 28 to the storage device 1 . The storage device 1 receives the sample container ID at the communication unit 15, and the calculation unit 11 associates the test request ID with the sample container type indicating the type of sample container 6 that matches the type of the sample container 6 indicated by the acquired sample container ID. Then, the sample container ID is stored in the storage unit 13 by recording the sample container ID in the sample table 133 . By storing the sample container ID, the sample contained in the sample container 6 is associated with the test request ID and the subject ID. It becomes possible to manage the sample based on the sample container ID.

The collection support device 2 next outputs the sample container ID in association with the test request ID and the sample container type (S9). In S9, the calculation unit 21 collects the acquired sample container ID as the sample container ID associated with the test request ID and the sample container type indicating the type of sample container 6 that matches the type of the sample container 6 indicated by the acquired sample container ID. The collection support image added to the support image and with the sample container ID added is displayed on the display unit 26 .

FIG. 12 is a schematic diagram showing an example of the collection support image after acquiring the sample container ID. FIG. 12 shows an example in which the sample container ID of the sample container 6 whose sample container type is sample container C is acquired. The obtained sample container ID is displayed in association with the test request ID and the sample container type indicating the sample container C. FIG. By outputting the sample container ID in association with the sample container type, the worker 51 confirms the sample container ID, and compares the type of the sample container 6 for which the sample container ID is acquired and the type of the sample container 6 indicated by the sample container type. and can be verified to match. This prevents the type of sample container 6 containing the sample from being mixed up.

The collection support device 2 next outputs an image of the sample container 6 with a mark indicating that the sample container ID has already been acquired (S10). In S10, the calculation unit 21 adds a mark to the image of the sample container 6 of the type indicated by the acquired sample container ID, and displays the marked image on the display unit 26 superimposed on the collection support image. If there is a sample container 6 for which a sample container ID has not yet been acquired, the calculation unit 21 also displays the image of the sample container 6 that has not been marked. FIG. 12 shows an example of an image of the sample container 6 to which a mark 262 indicating that the sample container ID has already been acquired is added. Since the sample container ID of the sample container 6 whose sample container type is the sample container C has been acquired, a mark 262 is added to the image of the sample container 6 whose sample container type is the sample container C. FIG. By displaying the mark 262, the operator 51 can confirm the appearance of the sample container 6 whose sample container ID has already been acquired. When acquiring another sample container ID continuously, the error of acquiring the sample container ID again from the sample container 6 whose sample container ID has already been acquired is suppressed.

The collection support apparatus 2 then determines whether or not there are check items associated with the test request ID and the sample container type associated with the acquired sample container ID (S11). In S11, the calculation unit 21 determines that the information related to sample collection acquired in S1 includes a confirmation item associated with the sample container type indicating the type of sample container 6 that matches the type of the sample container 6 indicated by the acquired sample container ID. Determine whether or not The calculation unit 21 may access the sample table 133 and determine whether or not there is a confirmation item associated with the test request ID. If there is no confirmation item (S11: NO), the collection support device 2 advances the process to S16, which will be described later.

If there are confirmation items (S11: YES), the collection support device 2 outputs a collection support image with a mark indicating that there are confirmation items (S12). In S<b>12 , the calculation unit 21 adds a mark indicating that there is a confirmation item to the collection support image in association with the acquired sample container ID, and displays the collection support image with the added mark on the display unit 26 . FIG. 12 shows an example of a collection support image with a mark 263 added to indicate that there is a confirmation item. A mark 263 is displayed near the sample container ID. By displaying the mark 263, the operator 51 can know that there are check items.

The collection support device 2 next outputs a confirmation request for confirmation items (S13). For example, when the operator 51 operates the operation unit 25 to specify the mark 264, the sample container ID, or the sample container type display portion on the collection support image, the operation unit 21 executes S13. . In S13, based on the information about sample collection, an image representing a confirmation request for check items associated with the acquired test request ID and sample container type associated with the sample container ID is superimposed on the collection support image and displayed on the display unit 26. indicate. The calculation unit 21 may access the sample table 133 and output a confirmation request for confirmation items based on the recorded contents of the sample table 133 .

FIG. 13 is a schematic diagram showing an example of an image representing a confirmation request for confirmation items. FIG. 13 shows an example in which the test request ID "001" and the sample container type "sample container C" are associated with the "medicine name" as a confirmation item. An input image for inputting a specific drug name as the content of the confirmation item is displayed.

The collection support device 2 then receives confirmation of the contents of the confirmation items (S14). In S14, for example, the operator 51 confirms the contents of the confirmation items, and the operator 51 operates the operation unit 25 to input the contents of the confirmation items, and the calculation unit 21 acquires the contents of the confirmation items. . In the example shown in FIG. 13, the drug name is entered, and the content of the confirmation item "medicine name" is entered by designating the portion representing "OK" on the image. The input of the contents of the confirmation items may be of a selection type.

The information related to sample collection associated with the test request ID includes designation as to whether confirmation of confirmation items is essential or optional. When the confirmation item is arbitrary, the operator 51 operates the operation unit 25 and designates a portion representing "cancel" on the image, whereby the calculation unit 21 acquires confirmation of the content of the confirmation item. S14 may be ended in a state in which it is not performed.

Similarly, the processing of S13 and S14 is performed when the check item is other than the "medicine name". When a plurality of inspection items and a plurality of confirmation items are associated with one sample container type, the calculation unit 21 may repeat the processes of S13 and S14 a plurality of times. Alternatively, the calculation unit 21 may output confirmation requests for a plurality of confirmation items in S13, and acquire the contents of the plurality of confirmation items in S14.

The storage device 1 then stores the contents of the confirmation items in association with the test request ID, sample container type, and sample container ID (S15). In S<b>15 , the calculation unit 21 transmits the contents of the acquired confirmation items from the communication unit 28 to the storage device 1 in a state in which they are associated with the test request ID, the sample container type, and the sample container ID. The storage device 1 receives the content of the confirmation item at the communication unit 15 . The calculation unit 11 stores the contents of the confirmation items in the storage unit 13 by recording the contents of the confirmation items in the sample table 133 in association with the test request ID, the sample container type, and the sample container ID. For example, the confirmation input URL is used to record the contents of the confirmation item. By recording the contents of the confirmation items in the specimen table 133, the information required for the clinical examination is recorded, and appropriate clinical examination can be performed using the recorded contents of the confirmation items.

After S15 is completed, or when there are no confirmation items in S11, the collection support apparatus 2 determines whether or not all sample container IDs to be acquired have been acquired (S16). In S16, the calculation unit 21 determines whether sample container IDs have been acquired for all sample container types associated with the test request ID. The computing unit 21 may access the sample table 133 and determine whether or not specific sample container IDs are associated with all sample container types associated with the test request ID.

FIG. 14 is a schematic diagram showing an example of a collection support image in a state where all sample container IDs have been acquired. A sample container ID is associated with each of a plurality of sample container types, and a mark 262 indicating that the sample container ID has already been acquired is added to all the images of the multiple types of sample containers 6 . The worker 51 can confirm that all sample container IDs have been acquired.

If there is a sample container ID that has not been acquired (S16: NO), the collection support device 2 returns the process to S5. If a plurality of sample container types are associated with the test request ID, the processes of S5 to S16 are repeated by the number of sample container types. In the processing of S5 to S16 from the second time onward, in a state where the sample container ID is acquired from one sample container 6, the sample container ID is acquired from another sample container 6, the sample container ID is stored, and the sample container type is stored. is output in association with the sample container ID. Even when a plurality of types of sample containers 6 are used in a clinical test for one subject, the sample container IDs of the plurality of types of sample containers 6 are stored, and each sample container 6 containing a sample is stored. Mistaking the types is prevented.

When all the sample container IDs to be acquired have been acquired (S16: YES), the collection support device 2 outputs the amount of sample to be contained in the sample container 6 (S17). In S17, the calculation unit 21 refers to the information related to sample collection associated with the test request ID, and uses the value of the total sample collection amount associated with the sample container type as the sample collection amount. is added to the image of the sample container 6 indicating the sample container 6 , and the image of the sample container 6 to which the collection amount is added is displayed on the display unit 26 .

FIG. 15 is a schematic diagram showing an example of outputting the sample collection amount. A sample collection amount value is added to the image of the sample container 6 associated with each sample container type. The specimen collection volume value is the total specimen collection volume value associated with the specimen container type. The operator 51 can confirm the amount of sample to be stored in each sample container 6 by outputting the value of the amount of sample to be collected.

After that, the operator 51 performs the work of collecting the sample from the subject. For example, operator 51 collects blood. Further, the operator 51 stores the collected sample in the sample container 6 in which the acquired sample container ID is recorded. After the sample collection is completed, the collection support device 2 receives that the sample has been collected (S18). In S18, the operator 51 operates the operation unit 25 to input information indicating that the collection of the specimen has ended, and the calculation unit 21 accepts that the collection of the specimen has been completed.

The storage device 1 then stores that the specimen has been collected (S19). In S19, the calculation unit 21 transmits information indicating that the sample has been collected from the communication unit 28 to the storage device 1 while being associated with the test request ID, the sample container type, and the sample container ID. The storage device 1 receives the information at the communication unit 15 . The calculation unit 11 records that the sample has been collected as a status in the sample table 133 in association with the test request ID, the sample container type, and the sample container ID. memorize to By recording in the specimen table 133 that the specimen has been collected, it is recorded that the specimen has been collected and stored in each specimen container 6 .

FIG. 16 is a conceptual diagram showing an example of the contents of the sample table 133 after samples are collected. A sample container ID and details of confirmation items are recorded in association with each sample container type associated with one test request ID, and as a status, it is recorded that the sample has been collected. The sample table 133 organizes which sample container 6 contains the sample used for the clinical test identified by the test request ID. Further, in association with the sample container ID, the sample table 133 records which test item of which clinical test the sample contained in each sample container 6 is used for. In this way, the sample table 133 manages information necessary for clinical testing in association with the test request ID and the sample container ID.

After S19 ends, the test support system 100 ends the process for supporting sample collection. The processing of S1 to S19 is executed for each inspection request ID. Among the processes of S1 to S19, some or all of the processes described above to be executed by the arithmetic unit 21 of the collection support device 2 may be executed by the arithmetic unit 11 of the storage device 1. FIG. For example, the calculation unit 11 may perform processing by controlling the operation unit 25 and the display unit 26 of the collection support device 2 via the communication network N. FIG. The collection support device 2 and the storage device 1 correspond to the examination support device.

The collected specimens are sent from the medical institution 20 to the testing institution 30 while being contained in the specimen containers 6 respectively. At the testing institution 30 , the worker 52 uses the reception support device 3 to receive the specimen sent from the medical institution 20 . The reception support device 3 is a computer such as a PC, a smart phone, or a tablet computer. The reception support device 3 includes an operation unit that receives operations from the operator 52 , a display unit that displays images, and a reading unit that reads the sample container ID recorded in the sample container 6 . The reception support apparatus 3 acquires the sample container ID from the sample container 6, and confirms the information recorded in the sample table 133 in association with the sample container ID.

In the laboratory 30, samples are managed based on the sample container IDs, and clinical tests using the samples are performed according to information recorded in the sample table 133 in association with the sample container IDs. The output device 4 is a computer such as a PC, smart phone, or tablet computer. The output device 4 outputs progress or results of clinical examinations. Furthermore, the results of clinical examinations are stored in the storage device 1 . When a plurality of inspection institutions 30 exist, the storage device 1 communicates with the reception support device 3 and the output device 4 provided in the plurality of inspection institutions 30 via the communication network N. The clinical test results stored in the storage device 1 are referred to by the medical institution 20 and notified to the subject.

As described in detail above, in this embodiment, the sample container ID is recorded in advance in the sample container 6 , and the test request ID and the sample container type are recorded in the sample table 133 . The medical institution 20 acquires the sample container ID from the sample container 6, and records/outputs the sample container ID in association with the test request ID and the sample container type. A sample container ID is recorded in the sample container 6 in advance, and the sample is managed based on the sample container ID obtained from the sample container 6 . The medical institution 20 does not need to perform work for assigning the sample container ID to the sample container 6, such as creating a label 61 in which the sample container ID is recorded and attaching it to the sample container 6. FIG. As a result, the amount of work involved in sample collection at the medical institution 20 is reduced.

The sample container ID includes information indicating the type of sample container 6 . By outputting the acquired sample container ID and sample container type, the operator 51 confirms that the type of the sample container 6 whose sample container ID is acquired matches the type of the sample container 6 indicated by the sample container type. can do. This prevents the type of sample container 6 containing the sample from being mixed up.

In addition, in this embodiment, samples are managed using sample container IDs recorded in advance in the sample container 6, so there is no need to build a system for handling sample container IDs independently for each medical institution 20. This reduces the cost of the system required for clinical testing.

In this embodiment, the operator 51 selects the specimen container 6 to contain the specimen by himself/herself. There may be.
